Grow Calendula for use in healing salves, as edible flowers, and for sunny color in cutting and herb gardens. A frost-tolerant annual, Calendula creates a long-lasting garden display. Make 2-3 successive sowings 2-3 weeks apart for continuous blooms from summer until heavy frost. Calendula blossoms are also rich in carotenoid and can be used as dye. Its flowers are used in traditional medicine for antiseptic tinctures and healing skin ointments. We offer Calendula varieties that show outstanding cut-flower performance, as well as a high-resin variety for medicinal use.
